Letztlich ist eine Antriebsvorrichtung für Gewindekerne von Spritzgießwerkzeugen bekannt (
Zum Herstellen von mit Innengewinden versehenen Spritzgießteilen ist es erforderlich, einen Gewindekern derart in der Kavität eines Spritzgießwerkzeuges anzuordnen dass dieser von einer eingespritzten Schmelze umschlossen werden kann und nach dem Erkalten der Schmelze mit einer Rotationsbewegung bei gleichzeitiger gewindesteigungskonformen Axialbewegung aus dem Innengewinde des erzeugten Spritzgießteiles „herausgeschraubt” werden kann. Um das Innengewinde des erzeugten Spritzgießteiles bei diesem Vorgang nicht zu beschädigen ist es zwingend erforderlich, dass die gewindesteigungskonforme Axialbewegung des Gewindekerns beim Herausschrauben des Gewindekernes nicht vom Innengewinde des Spritzgießteiles sondern vom Leitgewinde einer Gewindeausschraubvorrichtung erzeugt wird. Es ist Stand der Technik, dass die Übertragung des Drehmomentes des Antriebsmotors auf einen Gewindekernhalter indirekt erfolgt, beispielsweise über ein Mitnehmerrad oder ein Schneckenrad.For producing internally threaded injection-molded parts, it is necessary to arrange a thread core in the cavity of an injection mold that this can be enclosed by an injected melt and after cooling the melt with a rotational movement with simultaneous thread pitch-compliant axial movement of the internal thread of the injection molded part "unscrewed " can be. In order not to damage the internal thread of the injection molded part produced in this process, it is imperative that the thread pitch-compliant axial movement of the threaded core when unscrewing the threaded core is not generated by the internal thread of the injection molded part but by the Leitgewinde a Gewindeausschraubvorrichtung. It is state of the art that the transmission of the torque of the drive motor to a threaded core holder takes place indirectly, for example via a driving wheel or a worm wheel.
Die benannten Gewindeausschraubvorrichtungen weisen alle den Nachteil eines relativ hohen technischen und baulichen Aufwandes auf und beanspruchen auf Grund der indirekten Drehmomentübertragung ungewollt viel Einbauraum.The named Gewindeausschraubvorrichtungen all have the disadvantage of a relatively high technical and structural complexity and claim due to the indirect torque unintentionally much installation space.
Aufgabe der Erfindung ist es eine Antriebsvorrichtung für Gewindekerne von Spritzgießwerkzeugen zu schaffen, bei der der fertigungstechnische Aufwand gering ist und bei der das Drehmoment eines Antriebsmotors bei geringer Anzahl von Bauteilen Einbauraum sparend direkt auf einen Gewindekernhalter übertragen wird.The object of the invention is to provide a drive device for threaded cores of injection molds, in which the manufacturing effort is low and in which the torque of a drive motor with a small number of components installation space saving is transferred directly to a threaded core holder.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Hauptanspruchs gelöst. Ausgestaltungen der Erfindung sind in den Unteransprüchen dargestellt.According to the invention the object is achieved by the features of the main claim. Embodiments of the invention are shown in the subclaims.
Der Vorteil der Erfindung besteht darin, dass die Übertragung des Drehmoments des Antriebsmotors auf den Gewindekernhalter durch den Einsatz von Mitnehmerstiften erfolgt. Hierdurch lasst sich eine sehr kurze Gesamtbaulänge eines Antriebsstranges mit kombiniertem Axialausgleich realisieren, da die Mitnehmerstifte im Bauraum radial um die Gewindekernaufnahme im Gewindekernhalter angeordnet sind. Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert. Die dazugehörigen Zeichnungen zeigen:The advantage of the invention is that the transmission of the torque of the drive motor to the threaded core holder is effected by the use of driving pins. This makes it possible to realize a very short overall length of a drive train with combined axial compensation, since the drive pins are arranged in the installation space radially around the threaded core receptacle in the threaded core holder. The invention will be explained in more detail with reference to embodiments. The accompanying drawings show:
